Emery made only two alterations to the side which won 2-1 in West Yorkshire as Petr Cech came in for Bernd Leno in goal and Granit Xhaka returned from a groin injury to replace Lucas Torreira.

But, with Lacazette having a second-half equaliser correctly ruled out for offside before the France striker was sent off for swinging an elbow in frustration towards Aleksandar Filipovic with five minutes remaining, Arsenal slipped to a narrow loss at the Borisov Arena.

With no game before next Thursday’s return leg at the Emirates Stadium, Emery believes his squad will have the ability to turn things around and secure progression.

“I trust in our players and I trust in our stadium and supporters,” he said.

“There are two matches. Tonight’s match is important but we can’t (be knocked out), we are going to play a second match next week. I trust in our work to prepare for the next match and to have a different result in the Emirates Stadium.

“It’s a difficult match. Next week we are going to play another 90 minutes and I am sure it is going to be different.

“Today the first half was a good performance for us, we had chances to score, sometimes last week our chances were a goal and today is not.

Emery also revealed he spoke to Lacazette in the immediate aftermath of his red card and warned him to not let his temperament get the better of him.

“I didn’t see the action but we spoke and frustration needs controlling,” the Spaniard replied when asked about the sending off.

Letting the team down like that is the worst feeling..I should have stayed calm but it’s not always easy.. Sorry 😣There are still 90 minutes to play and I believe that my teammates will make it to the next round.. #COYG#Laca
